form of high spliceabove the usual reinforced heel which. ischaracterized by stripes knit into the fabric of the stocking onopposite sides adjacent the selvedge edges and ar-:

ranged so that when the stocking is sewed up the back scam the stripesform in effect an 1nverted V-shape design to provide-a'means forvisually slenderizing the ankle and to-provide j an ornamentalconfiguration above the low shoe of the wearer. M i The primaryobject'of the invention is to provide a simple form of machine, or rather asimple form of attachment to a conventional form of straight barstocking knitting ma chine, for mechanically controlling the feeding ofyarn or threadto the needles of the .machine in'such way as will producethe desired form of ornamentaldesign inthe stock- 0 ing as an incidentof the usual knitting operation. V e n More specifically, an object-ofthe invention is to provide a'simple formiofcontrol for F two of theusual thread carrier bars in order to producethin stripe'sfextending atan angle to both the courses-and to the wales of the knitting in orderto produce the desired dc;

slgn.

Among the other'obj'ects of the invention is to provide a thread carriercontrol which canbe quickly brought into operation at the desiredpointinthe progress of theknitting ofthe stocking; to providea-simpleform of adjustment by means of which the width of the desired stripesmay be readily set and quickly changed at will to some other required.width; to provide as part-of the con trol means for varying theangularity of one or more of the stripes and inwhich when once showingcertain parts of a conventional form of stralght bar knitting machineequipped the stocking.

set the required stripe or stripes may be knit into the fabricautomatically and without necessity of further attention on the part ofthe operator until the desired length of stripe has been knitted. I

,Various other objects and advantages of theinv'ention will be in partobvious from an inspection of the accompanying drawings and in part willbe more fully set forth in the fol lowing particular description of oneform of device embodying the invention, and the invention also consistsin certain new and novel features of construction and'combination ofparts hereinafter set forth'and claimed.

In the accompanying drawings, p Fig 1 is a view largely diagrammaticwith a preferred embodiment of my invent on and shown in position attheterminat10n of the stripe knitting !operati0n;'and

Fig. 2 1s an enlarged vlew 1n slde elevatlon 7 of either one of thestripe width defining stops shown in plan in Fig. 1. V

In the drawings, there is shown three of the usual thread carrier bars10, 11, 12, forming part of a straight bar knitting machine of the typenow in general use in knitting full fashioned stockings and in whichthere are usually a much larger number of such bars. It is understoodthat these bars are controlled at one end by meansof a jacquard orotherpattern controlling device for regulating the throw of the bars andfor timing 3 the action of thesebars in knitting'the. different parts ofthe stocking. as is well known in knitting machines of the type underdiscussion. i

One such bar12 is provided with a thread carrier13, in this casebeingthe thread. carrier to supply the needles 14 with thread to knit thestocking from one selvedge edge 15 v to theotheredge 16 and this bar 12and its associated carrier 13 maybe' regarded as rep resentative of theother similar bars and carriers used in knitting the difierent parts ofBars-10 and 11 are provided respectively with a left design thread oryarn carrier 17 and 'a'right design thread or yarn carrier 18 but it isunderstood that these yarn carriers are designed normally to knit otherparts of the stocking blank. From the showing in Fig. 1 it is to beunderstood that the carrier 17 Supplies threadto the needles used Thepresent disclosure features the use of a pair of supplemental stopsorrather. stripe width-defining controls 21, one for each of the rods 16and 11 which in turn control the recip-incating yarn or thread carriers'17 inrc'l -:-As"the construction is the same for the controls of bothbars the -detailed description of either; 'onewill be 'sufiieient'fortheother.

The controls are formed of angle plates 22; avert-ica-Hy upstandingflange -23- of which'is fastenedto'the' forward side :ofit-s associatedbar by meansof rivets-24. H The upper flange 25 extends across the topof the bar as shown particularly in Fig. '1 and is provided with twolongitudinally spaced apart upstanding fingers 26 and 27. These fingersmay include horizent ally extending set or stop. screws 28 y and 29designed to be 'adjhsted to provide a variable space 30 therebetween. A,relatively hied stop "or abhtmerit31 carried atxthe forward end ofcari'iageBQ is designed tp be prosjected into the space 30asparticularly showh in Fig. 2. The two carriages 32 are slid-ably mountedupon onfexof the longitudi na'l bars 33. forming one of the parts of theconventional form of knitting machine.- The abutment '31is in the for'niof a rectangular bar and is s'li'd'ably mounted in its associatedcarriage for vertically adjusted movement so that it may: be lowered atWill into position between the opposing ends of the set screws 28 "and29 as shownin Fig. 2', or may be elevated s'o that the bar and theatta'cl'lm-en't 7 plate 22 may lie-free to recipro'cate'beneath theelevated abutment bar 31. Bar 31 may be secured in either it's elevatedor in its lowered operative position by means of a "conventional form015a binding screw '34.

It is the intent to can'se the relatively fixed abutments "31togradually approach each other as the kI-iitting oi the-stocking :pro'gresses course after course towards it"s-toe end andthu's cause thestripes to approach each other as shown in the stocking-1 hlank- 35,Fig. 1'. or the purposeof causing thethr'ead carriers 17., and 18forming the stripes. 1'9 and 20 to approach eachiother, the carriages 32carrying the abntments engage a right and "courses left hand feed screw36 andwhich feed screw is inturn advanced by some conventional form offeed ratchet 37. coupled to work in synchronism with theother parts ofthe knitting operation; In the instant case the parts are so timed thatfive courses indicated by parallel; lines. in block or-set 38 are knitin eachstripefbefore the i'a'tchet madva'nes the feed screw soas todisplace the stops 22 a short clistanceinwar dly from its previousposition tojfoinithe "fie-Kt "siiceeding block 39 of five It willbeadvanced towards each other and in the direction parallel to thereciprocating bars with a step bystep movement.
